Alias Short Subscriber Identity
Radio
A two-way communication device used
for voice and data.
Alias Short Subscriber Identity (ASSI)
The Tetra address corresponds to the Individual
Tetra Subscriber Identity (ITSI). It includes in
addition to the Mobile Country Code (MCC), the
Mobile Network Code (MNC) nor the 7- or 8-digit
subscriber short identifier, Short Subscriber
Code (SSI), the allocation of mobile radio
equipment to a private or public service
produces.

European Telecommunications
Standards Institute (ETSI)
active in the smart card field, building European
standards where there are gaps in the ISO
standards. ETSI card standards work is based
on ISO standards where published.

Short Data Service (SDS)
bearer service that transfers information from
one interface to another.
Main Control Channel (MCCH)
control channel at a site. The channel is used by
radios to register on the system and to request
and setup speech calls with other radios.

Over-The-Air-Rekeying protocol
(OTAR)
Used in connection with Air Interface
Encryption.

Downlink
The radio frequency
communications path from the BTS to the radio.
Also referred to as the BTS transmit path.

components excluding the mobile equipment that
is the CNE and all the remote site equipment.

Individual Short Subscriber Identity
(ISSI)
TETRA term for a unique, individual ID
assigned for each radio.

Talkgroup
A uniquely named group of radios
that can share calls and messages. A talkgroup's
normal communications do not require
interfacing with other talkgroups. Typically, the
majority of a radio user's communications are
within their own talkgroup.
Public Switched Telephone Network
(PSTN)
The telephone network, traditionally
the wired network, that requires the public user
to address or dial the destination using a
"telephone number" for a temporary connection.
Group Short Subscriber Identity
(GSSI)
TETRA term, in Dimetra called Group
ID or Talkgroup ID.

Derived Cipher Key (DCK)
encrypt all uplink signaling (from radios to
infrastructure) and individually addressed
downlink signaling (from infrastructure to a
radio).
See also: Encryption
Common Cipher Key (CCK)
encrypt group and broadcast addressed
downlink signaling (from infrastructure to a
radio). Also used to protect ISSI identities.
